Improved egg-beater



`UNITED STATES PATENT OFFICE@ MOSES G. CRANE, OF BOSTON, MASSACHUSETTS.

IMPROVED EGG-BEATER.

To all whom it may concern.-

Be it known that I, MOSES G. CRANE, ot' Boston, in the county of' Suii'olk and State ot' Massachusetts, have invented an Improved Egg-Beater; and I do hereby declare that the art to practice it.

The invention relates to the construction of that class of egg-beaters in which a seriesof wires projecting from a vertical spindle are rapidly rotated in opposite directions by a system ot' gearing driven by hand.

In some rotary egg-beaters two series ot'wires are employed7 tixed to separate spindles, one of which spindles is tubular with the other passingf through it, the two series receiving motion in the opposite directions. This construction is objectionable from requiring too tine and too costly an arrangement of mechanism. Other beaters are now constructed in which one set of wires is employed, the wires being driven rapidly and alternately irst in one and then in the opposite direction; and my present improvements have particular reference to this latter arrangement.

Such a mechanism was patented by me in the patent No. 48,525, but the construction therein shown is in some respects objectionable t'rom the peculiar arrangement of the driving mechanism, which objections are obviated in the mechanism or arrangement forming the subject of my present improvements.

The invention consists, primarily, in the peculiar construction or arrangement of the gearing mechanism for driving the spindle; also, in the construction by which the beater is` readily applied to and removed from a table, or may be grasped by hand, as may be desirable 5 also, in the manner of applying the wires to the spindle.

The drawings represent at A a plan, at B a front elevation, and at O a side elevation, of an egg-beater embodying my improvements. D shows a reversed plan ofthe reducing or commingling wires.

a denotes a vertical spindle extending through and supported in position in bearings made in the top and bottom of a standard or post, b. To the lower part of this spindle the beater-wires c are fastened, and upon its upper part are fixed two horizontal pinions, d e, one on top ofthe other, they being preferably made integral. The standard I) has an ear or projection, j', in which is a pin, g, upon which a compound gear or gear-frame, h, rotates horizontally. This frame has two segment-gears, t' and h, the gear t' being an external gear in the plane otl and meshing with the pinion d on the spindle a, and the gear It' being au internal gear meshing into the pinion c. The gearframe has a handle, Z, by which itis rotated horizontally, bringing the segment-gears t' 7.2 respectively and alternately into connection with the spindle-gears, and driving the spindle and its wires alternately in opposite directions, as will be readily understood.

This construction and arrangement of the gears is preferable to my construction, referred to above, because the handle is more easily to a table, and the two pinions tl c may be made in one casting.

The rear side ofthe standard b is made vertical in one direction, as seen at C, and the two sides or edges o pare inclined in a vertical direction, as seen at I3, while the standard is made triangular in cross-section, as seen at E.

To attach the instrument toa table, a plate, q, is used, said plate being screwed to the table as a fixture, and having four lingers or hooks, r, projecting from its face and inclining inward, as seen at E, the two lower ones being slightly nearer together than the upper ones.

lower part ot the standard is carried against the plate and between the hooks, and it is then slipped down till it wedges between the tingers, as seen at B, securing the standard firmly and immovably to the table while the beater is operating, and allowing it to be easily removed therefrom. The form of the standard allows it to be conveniently grasped in one hand, while the other hand drives the gearing mechanism, and thus the instrument may be used in either way, as may be desirable.

In the construction shown in my patent above referred to no provision was made for attachment of the instrument to a table, and the arrangement of the gears prevented the hand from grasping the frame around the manipulated by hand when the beater is iixed f In applying the beaterI thereto the narrow or spindle, such frame having` to project on one side; but by this construction the-arrangement of the gears to rotate horizontally allows the hand to grasp the standard entirely around the spindle, rendering it much easier to hold the instrument when operating it than in the former construction. rlhe rotary wires @,which are shown as six in number, are fastened to the spindle a as follows: A piece of wire long enough fortwo is bentin the center into a circular forni, as seen at D, and so that it may almost encircle the spindle a, the wire from the center outward being bent so that it will extend radially from the spindle and then upward, so as to have its upper ends joined to the spindle, as seen at B and C. Three pieces of nearly the saine length being thus treated, the central parts of all are applied horizontally to the lower end of the spindle, as seen in the drawings, and having been arranged so that they stand at regular intervals, are then soldered together` and to the spindle. rlheir upper ends being brought up to the vconstructed and arranged to rotate horizontally, substantially as set forth.

2. In combination with the standard b, spindle a, and wires c,- arranged and operating as described, the plate q, with its iingers r arranged to hold the standard I), substantially as described.

In witness whereof I have hereunto set my hand this 9th day ot'May, A. D. 1866.

MOSES G. CRANE.
